MUFFLER FOR- ENGIVNVES.

SPEGIFIGATION forming part of Letters Patent No. 6'75,4 98, dated June 4, 1901. Application filed February 26,1901. Serial No. 48,928. (No model.)

To aZZ whom it may concern.-

Be it known that I, HIRAM M. QUICK, a citizen of the United States of America, residing at No. 214 Van Houten street, in the city of Paterson, in the county of Passaic and State of New Jersey, have invented certain newand useful Improvements in Mufflers for Engines, of which the following is a specification, reference being had therein to the accompanying drawings. v

One object of my invention is to provide a means for mufliing or deadening the sound of the exhaust of an engine in'which the motive force is produced by the explosion of a gaseous body,- which is usually effected by or' through the mediumof an electric spark.

A further object'of the invention is to obtain a simple and effective muifling device that will be durable and inexpensive.

The invention consists of two or more tubes, cylinders, or conduits of suitable size and shape adapted to be held and fit the smaller within the larger, leaving an annular space between the larger and the smaller-,the innermost being provided with a longitudinal slot in the bottom thereof and the next larger one being provided at the top with a similar longitudinal slot or opening, and'the outermost, if there are three concentric cylinders or tubes, as shown in theaccompanying draw ings, is provided underneath with a longitu dinal slot or opening also, so that the exhaust has to pass from the exhaust-pipe to the innermost cylinder of them-uffler, thence to the next cylinder, then tozthe outer one, and thence to the atmosphere.

Means may be provided forcleaning the cylinders of unconsumed matter passing from the exhaust-pipe into the mufifler,-if desired; but the arrangement of receptacles or chambers of any suitable shape provided with oppositely-located openings to facilitate the passage of the exhaust to the atmosphere, said receptacles being locatedthe one within the other, leaving aspace between the larger and the smaller, is what I wish to limit myself to and which will be more definitely indicated hereinafter in the claim. It is obvious that said receptacles may be of various forms for instance, octagonal, square, cylindrical, conical, or funnel-shaped-mcreasrng graduate, and outer cylinders.

.any size or formation, while only one-the cylindrical formationis shown in the drawings. It is deemed sufficient to illustrate the nature and essential principle of my invention.

In the drawings, in which similar letters of reference indicate like parts in the various views, Figure lis a front View of my mufitler connected with the exhaustpipe. Fig. 2 is an end view where the muffler is connected with the exhaust-pipe. Fig. 3 is a sectional view through line a: a; in Fig. 4-, showing exit for exhaust from the innermost, intermedi- Fig. 4 is a longitudinal sectional view through muffler on line y y in Fig. 2. r A

A and A are the ends of the muffler, which are held together by screw rods and nuts a a or by other suitable means.

B is the outer tube or cylinder, and b the longitudinal opening or slot therein to permit the escape of the exhaust, which passes to the atmosphere as indicated by the arrow in Fig.

Oisthe intermediate cylinder, and c the longitudinal slot or opening therein to permit the escapeof the exhaust therefrominto the outer cylinder, as indicated by the arrow in Fig. 3.

D is the innermost tube, which is connected I with the exhaust-pipe, and dis the slot or opening which permits the passage of the exhaust therefrom to the intermediate cylinder,

as shownrin Fig. 3.

Instead of the longitudinal slots 1), c, and d itis obvious that perforations in the various o cylinders may be substituted without departing from the essential principles or scope of my invention.

vWith this description of my invention, what I claim is- Ina muffler for explosion-engines, two heads provided on their inner faces with concentric annular grooves, one of said heads having a central aperture, in combination with a tube passing through the central ap- 10o erture in one head, and into one of the annular grooves in the opposite head, said tube being provided with a longitudinal slot in I the passage of the exhaust through said tube,

provided with a longitudinal slot in the top In testimony whereof I affix my signature thereof, and a still larger-or outermost cy1in in presence of two witnesses.
